It sure isn’t our mentally ill and disabled children. Teachers are inadequately trained to recognize and deal with mental illness, and most training to deal with neurodivergent or disabled kids trades in misconceptions, ignoring the basic rule that every disabled person should be approached with an assumption of competence.

Mentally ill and disabled students already receive a disproportionate amount of attention from school resource officers—18 percent of disabled secondary students nationwide get suspended, versus 10 percent of the non-disabled students. School staff often read escalating emotions as threatening. My own autistic kid got agitated in a class headed up by a substitute teacher. He was taken down to the ground and handcuffed by the school guard, when a few minutes outside of the room to cool down would have achieved the desired effect.

We also know that children as young as five years old can be suicidally depressed and make attempts to kill themselves, often impulsively. Suicide is the second leading cause of death for youth between ages 5-24. Access to firearms increases the likelihood that a child will attempt suicide; with a gun, they’re much more likely to be successful. In fact, youth are 60 percent more likely to commit suicide with a gun than they were in 2007. How safe are our schools if they increase access to guns for suicidal kids? What kind of horror would it be if “suicide by teacher” became a thing?

And it sure isn’t children who exist where these issues intersect. The majority of US teachers are white women, and implicit bias research shows that, despite training and intention to reach cultural competence, black and brown students are perceived as larger, older, and more aggressive. Add in the unpredictable behavior displayed by mentally ill and disabled students, and the chance of teachers misinterpreting their actions as threatening skyrockets. Disabled students of color are already suspended more often than any other group—1 in 4 for boys, 1 in 5 for girls. Add guns, and the stakes become unbearably high.

In a country where teachers assume the cost of the most basic classroom supplies like books and paper, we’re also increasingly expecting them to lay down their lives in a school shooting scenario. I don’t know a teacher who wouldn’t already do that, to be honest. But in situations where trained, experienced gun users fail to offer a viable defense against a shooter, teachers would be expected to protect the lives of their students as if they were cops or soldiers. That doesn’t even address how law enforcement would react upon entering a school with an active shooter and an array of other people brandishing guns, some of whom could be as young as 22 and of any race or gender.

So again I ask: whose children are safer if we arm teachers? It sure isn’t mine, and it sure isn’t yours.
